Joystick
Abstract
A joystick controller comprises a base to which an upright element is
fixed, and a tubular joystick positioned around the fixed element and
pivotally mounted to the base. Electrical contacts are carried by the
joystick and make selectively with the fixed element depending on the
direction in which the joystick is tilted. The base has a curved bottom to
seat equally in the right or left and of the user, but has portions which
can be hinged open to reveal a flat bottom which will sit on a desktop and
be retained thereon by suction pads.

Description
BACKGROUND OF THE INVENTION
This invention relates to a joystick controller, e.g. for use with
computers when playing games.
In general known joystick controllers are either hand-held or arranged for
mounting on the desk top and provided with suction pads for holding them
down. The hand-held joystick controllers are generally suited to right
handed people only.
SUMMARY OF THE INVENTION
In accordance with this invention as seen from one aspect, there is
provided a joystick controller comprising a base having a joystick
projecting upwardly therefrom, the base being shaped for holding in the
palm of the hand but having a portion which is displaceable to enable the
joystick to be mounted on a desktop, the base being provided with a
suction pad for holding the joystick to the desktop when said portion is
appropriately displaced.
Preferably the base of the joystick is formed with a curved bottom suited
equally for holding in the right or left hand. The displaceable portion of
the base may be hinged outwards to form a flat bottom to the base, suited
for standing on the desktop. Preferably there are two portions which hinge
outwards in opposite directions and which are provided with respective
suction pads.
Known joystick controllers generally include microswitches, leaf switches
or small flexible tabs for effecting the different electrical contacts.
All of these have limited reliability. The electrical contacts are
generally disposed in the base of the joystick controller, with a tendency
for the base to be rather large.
In accordance with this invention as seen from another aspect, there is
provided a joystick controller, which comprises a base, an elongate
element fixed to the base and projecting upwardly therefrom, a tubular
joystick positioned around the fixed elongate element and pivotally
mounted to the base, and electrical contacts carried by one of the tubular
joystick and the elongate element arranged to make selectively with the
other of the tubular joystick and the element depending on the direction
in which the tubular joystick is tilted.
By removing the electrical contacts from the base and disposing them within
the joystick itself, more room is left in the base for other components
such as autofire circuitry. Also or instead, the base may be made smaller
to suit a smaller hand.
The electrical contacts are preferably direct-acting so as to be more
reliable. Preferably the contacts are adjustable for contact point
distance so that the feel of the joystick controller can be adjusted to
the user's preference. Further with these types of electrical contact, a
"fire" button can be mounted at the top of the joystick, which is
preferable to being positioned on the base.
Embodiments of this invention will now be described by way of examples only
and with reference to the accompanying
BRIEF DESCRIPTION OF THE FIGURES
FIG. 1 is a schematic vertical section through one embodiment of joystick
controller in accordance with the invention;
FIG. 2 is a cross-section on the line II--II of FIG. 1;
FIG. 3 is a schematic vertical section through the upper end of a modified
joystick;
FIG. 4 is a section on the line IV--IV of Fig. 3 shown with the electrical
contacts removed from their carrier insert; and
FIG. 5 is a schematic view of the components of the electrical contacts.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1, there is shown a joystick 20 projecting upwardly from
the base. The base 10 has two bottom portions 12, 12 which are hinged to
the upper portion 14 of the base at opposite edges 16, 16. The upper
portion 14 has a flat bottom periphery and the hinged portions 12, 12 have
flat surfaces which close onto the flat bottom of upper portion 14, as
shown. When the hinged portions 12, 12 are closed as shown, they present a
convex curved bottom surface 17 to the base, which is shaped for the
joystick to be held comfortably in the palm of the hand, equally whether
the right or left hand. However, when the portions 12, 12 of the base are
hinged outwards in opposite directions from the portion 14, a generally
flat bottom to the joystick base is presented, for it to be stood on a
desktop. Further, the flat surfaces of the hinged portions 12, 12 are
provided with suction pads 18, 18 for holding the joystick controller
firmly to the desktop.
Thus the joystick controller has particular versatility, being suited for
holding equally in the right or left hand or for mounting firmly on the
desktop.
The joystick controller comprises a centre pole 22 fixed to the upper
portion 14 of the base and projecting vertically upwards therefrom. The
joystick 20 itself comprises a tubular member disposed around the centre
pole, and journalled to the base portion 14 by means of a self-aligning
bearing 24. A resilient ring 26 encircles the pole 22 and serves to centre
the joystick 20 concentrically about the pole 22 when the user's grip on
the joystick 20 is released.
Referring particularly to FIG. 2 of the drawings, an annular ring is
mounted to the inner surface of the tubular joystick member, and divided
at intervals of 90.degree. around its periphery to form four electrical
contacts 28. According to the direction in which the joystick 20 is tilted
relative to the base and centre pole, one or another (or any adjacent
pair) of the contacts 28 will make with the centre pole at the top of the
latter, thus completing a respective electrical circuit (or pair of
circuits). As shown in FIG. 1, "fire" buttons 30, 32 may be provided, one
mounted in the closed top end of the joystick 20 and the other in the side
of the joystick 20, each being depressible against a spring bias to make
with the top or side of the centre pole 22.
In the modified embodiment shown in FIGS. 3 to 5, the "tilt" contacts are
adjustable. Thus, the tubular joystick element 20 is provided with a
moulded plastics insert 34 which mounts four contact plates e.g. 28a and
an adjustment screw 36. This adjustment screw bears against the outer,
inturned end of the contact plate 28a, and compression spring 38 acting
between this outer end of the contact plate and an abutment 40 of the
insert 34. Thus tightening of the screw 36 reduces the contact point
distance between the inner inturned end of the contact plate and the
centre pole 22.
